Meanwhile, the ongoing auction has vindicated CAG's criticism of the way the natural resources was allocated by the previous government, Commerce Minister Nirmala Sitharaman said Friday.

"The last CAG report on the coal block allocation was unfortunately unnecessarily criticised but today the figures and the way in which the coal block allocation has been designed by this government in a very transparent manner and has shown two things," she told reporters on the sidelines of an event.

"Certainly the CAG's position has been vindicated but I am underlining the larger issue here. Our position has been vindicated," Sitharaman added.
